HARROW.

SPECIFICATION forming part (if Letters Application filed August 25, 1882.

To (LZZ whom it-mcty concern:

Be it known that I, ISAAC LEMON, a citizen of the United States, residing at Nebraska City, in the county of Otoe and State of Nebraska, have invented certain new and useful Improvements in Harrows', of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to improvements in liarrows, and is more especially adapted to that class known as spring-tooth harrows.

The novelty consists in the peculiar construction and arrangement, in combination with a spring-tooth, of a twisted cutting-blade provided with a right-angular arm adapted to be securedto the under side of the tooth and beam, as will be hereinafter more fully set forth and claimed.

The object of my invention is to provide, in a spring-tooth barrow, a cheap and simple means whereby trash,weeds, and the like may be removed from and in advance of the teeth.

Figure l of the drawings is a representation of a plan of a part of a pair of beams and harrow-tooth, showing the clearing-blade in dotted lines. Fig. 2 is a side View of the same. Figs. 3 and 4 are views of the clearing-blade.

Referring to the drawings by letters, O in dicates the longitudinal and O the transverse beams of a harrow, which are mortised and secured together in the ordinary manner.

13 indicates a springtooth of the ordinary construction, and Aa cutting or clearing blade, which is preferably formed of steel, but may be made of any suitable metal. This cutter has a sufficient length of its upper portion twisted as shown, with its edges on a line with the sides of the cutting-blade, and then bent at right angles to the edges of the blade, to form a broad bearing for the cutter when in Opera Patent No, 295,124, dated March 11, 1884,

tion. It will be observed that I do not make the clearing-blade integral with the tooth of the harrow, and therefore, should a cutter be come broken or destroyed, it will not be nec essary, in order to replace it, to provide a new tooth, as the old cutter can be removed and a new one inserted.

In constructing the barrow, the verticalbolts are passed through perforations in the beams, or through perforations in the plates D and D on the upper and lower surfaces of the beams, as shown in Fig. 2 of the drawings. The tooth and bent arm of the clearing-blade are then inserted between the plate D and the beam 0, when nuts are applied to the bolts, as shown, and the tooth and blade firmly secured to the barrow-frame.

I am aware that a twisted and bent cutter is not new, and also that a cutter made into gral with a spring-tooth twisted and bent to travel in advance of the tooth is not new, and therefore do not claim such, broadly.

7 Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a spring-tooth harrow, the combination, with the spring-tooth B, of the cutter A, having its cutting-edge presented vertically in the direction of the line of draft, its upper end twisted and bent horizontally at right angles 7 to the cutting-edge, and adapted to travel directly in advance of the tooth, with the said bent arm of the cutter removably secured to the under side of the tooth, substantially as described, and for the purposes specified.

ISAAC LEMON.
